Description

Technical Field

[0001] The utility model relates to the technical field related to windshield wipers, and in particular to a snap-fit ​​fixed windshield wiper structure. Background Art

[0002] Generally speaking, wipers need to be connected to wiper arms. Since wipers will wear out after wiping water and dust for a period of time, wipers and wiper arms need to be detachable. The key to detachability is that the wiper is fixed with a fixing seat, and the wiper is detachably connected to the wiper arm through this fixing seat.

[0003] In order to reduce costs, the existing wiper structure uses a plastic part for the fixing seat or a plastic part for the bottom. Therefore, the fixing seat is connected to the steel sheet by opening a through hole for fixing on the steel sheet, and then the plastic part at the bottom of the fixing seat is melted by infrared heating or other heating methods, and flows into the through hole and solidifies to fix the steel sheet and the fixing seat. The steel sheet is a supporting component in the wiper.

[0004] The above-mentioned fixing method will add additional heating and waiting for curing, which will prolong the time of wiper production; at the same time, the hot gluing fixing method will cause the connected part to receive alternating stress when the wiper undergoes reciprocating scraping and grinding movements. The shape of the hot-glued part is uncontrollable, so it will easily break, resulting in unstable connection between the wiper and the wiper arm. Utility Model Content

[0023] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0024] like Figure 1-4 As shown, in this embodiment, a snap-on fixed wiper structure is provided, including a pair of steel sheets 6 and a fixing seat 1. The pair of steel sheets 6 are snap-on connected with the fixing seat 1. The bottom of the fixing seat 1 is integrally formed with a snap-on point 3 extending downward and protruding. The two outer sides of the fixing seat 1 extend downward and bend toward the middle to form a pair of snap-on parts 4. The middle of the steel sheet 6 is provided with a through hole snap-on connected with the snap-on point 3, and a notch is provided between the pair of snap-on parts 4. Specifically, during the assembly process, the steel sheet 6 is first inserted inwardly along the notch between the snap-on part 4 and the fixing seat 1, and then further slid inwardly for installation. The steel sheet 6 is a relatively thin component, and can undergo a certain elastic deformation during the installation process. After deformation and springing open, the steel sheet 6 can be snap-on connected with the fixing seat 1.

[0025] In this embodiment, the highest point of the buckle point 3 is provided with a limit vertex 2. The buckle point 3 is a rectangular structure in a plane. The highest point of the buckle point 3 is provided, that is, the limit vertex 2 is buckled with the steel sheet 6. The limit vertex 2 is extended and arranged obliquely toward the middle of the fixing seat 1, and is completely overlapped with the right-angled side of the through hole mentioned above to achieve the position of the multiple buckles of the steel sheet 6. Therefore, a right-angled side is provided at the extended side of the limit vertex 2, or the limit vertex 2 needs to be provided at the right angle of the extended side. In order to prevent the steel sheet 6 from tilting up and falling off at the set notch, the limit vertex 2 is provided at one end away from the groove. Therefore, even if the steel sheet 6 receives some torque, it is not easy to fall off from the fixing seat 1. The height of the limit vertex 2 is set to be greater than the thickness of the steel sheet 6, so it can play a supporting role. In this embodiment, four snap points 3 are preferably provided and the extended edges of the snap points 3 and the limiting vertices 2 are flush with the bottom surface of the fixing seat 1, so that they can be inserted by deformation during installation and can be limited again after rebounding.

[0026] In this embodiment, a pair of the steel sheets 6 are arranged at a distance from each other, a wiper strip 7 is clamped between the pair of steel sheets 6, an inwardly recessed sliding groove 8 is provided on the top of the wiper strip 7, and the wiper strip 7 is clamped on the steel sheet 6 through the sliding groove 8. The purpose of setting the distance is to clamp the middle part of the wiper strip 7. It is best that the middle part of the wiper strip 7 is not larger than the distance set between the steel sheets 6 to keep the wiper strip sliding.

[0027] In this embodiment, a pair of the steel sheets 6 are also sleeved on the top of a guide sleeve 5, which holds the edge of the steel sheet 6. At the same time, the guide sleeve 5 is provided with a guide strip extending to the top, which can effectively guide out some oncoming rainwater when in use. The guide sleeve 5 can further hold the two steel sheets 6 to avoid shaking. Fixed sleeves 9 are also respectively sleeved on both sides of the steel sheet 6; the fixed sleeves 9 are respectively fixedly connected to the two ends of the steel sheet 6, and the fixing method can be achieved by conventional means such as bonding. The fixed sleeve 9 can mainly limit the possibility of the guide sleeve 5 moving thereafter to achieve the reliability and stability of the overall wiper structure.

[0028] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
